Advances in Carbon Nanotubes and Carbon Coatings as Conductive Networks in Silicon‐based Anodes

Abstract Silicon‐based anode has high theoretical capacity but suffers from poor electrical conductivity, large volume expansion, and unstable solid electrolyte interphase (SEI). Adding carbon nanotubes (CNTs) and carbon coatings are both very effective methods for addressing the above issues. The intrinsic sp 2 covalent structure endows CNTs with excellent electrical conductivity, mechanical strength, and chemical stability, which makes them suitable for various energy storage applications, such as in lithium‐ion batteries (LIBs). Apart from the conductive network, CNTs can serve as current collectors, mechanical probes, and mechanical frameworks, and they have potential in the construction of next‐generation…
